Air Squared is a vertically integrated research and development (R&D) original equipment manufacturing (OEM) firm headquartered in Thornton, Colorado. Its operations include the design, fabrication, and production of oil-free scroll compressors, vacuum pumps, and expanders. Organized in two divisions, Air Squared Manufacturing handles volume assembly and production whereas Air Squared Inc. handles research and development.

## History

[edit]

In 1991, Robert Shaffer founded Air Squared Inc. in Cincinnati, Ohio[1] to license oil-free scroll compressors for medical device applications.[2] Air Squared's first patent was awarded in 1997 titled Scroll compressor having a tip seal.[3] In 2001, Air Squared Manufacturing Inc. was formed in Broomfield, Colorado. Operations were consolidated when both entities merged to form Air Squared Group Inc. in 2016. In 2022, all operations were relocated to Thornton, Colorado.
